Thank You for Turning in More than 133,000lbs. of Household Hazardous Waste DuringSpring Collection Day

Join communityvolunteers at our annualstream cleanup event aswe remove trash, litterand debris from one ofour local creeks. This isa great volunteeropportunity for scouts,civic groups, churchgroups, environmentalclubs and families.

CCWA’s Stormwaterstaff works throughoutthe year to educateresidents about thedamage stormwaterpollution does to ourlocal waterways andhow they can preventthis pollution frommaking its way into our drinking water. This event gets residentsinvolved in preserving and protecting our local waterways.

During our 2018 cleanup at Panhandle Park, more than 100 volunteersworked together to clean up around Hurricane Creek. Come join us thisyear as we clean another area in our county. For location and moreinformation, visit ccwa.us or call 770.960.5200.

The Clayton County Water Authority’s Stormwater Utility (SWU) isresponsible for all stormwater activities for unincorporated ClaytonCounty and the cities of Forest Park, Jonesboro, Lake City, Lovejoy,Morrow and Riverdale.These activities include Construction Plan Reviews and Inspections,Floodplain Management, Illicit Discharge/Illegal ConnectionInspections and maintenance of stormwater infrastructure within theroad right-of-way and directly connected to the right-of-way.This annual report is produced to show a summary of the activitiesthat have been performed by Clayton County Water Authority’sStormwater Utility over the past year and how your Stormwaterdollars are being used.

Connecting With Our CommunityStormwater staff participates in numerous Career Day events atClayton County Public Schools. Through these events, theycan connect with thousands of students and educate themabout the damaging effects of stormwater pollution and whatthey can do to protect our water quality.

CCWA staff also participates in the Metro North GeorgiaWater Planning District’s annual Southern Children’s WaterFestival. The festival is held at our Shamrock Community UseBuilding in Jonesboro every May. More than 400 second andfourth grade students from Clayton, Fulton, Henry, Fayetteand Rockdale County school districts participated in thishands-on day of water education. The goal of the event is to provide quality water education opportunities to as many students as possible andremind the kids about the direct connection we have on the quality and quantity of the water in our rivers, lakes, and streams.The photos show staff at Suder Elementary and the water festival.

CCWA’s StormwaterUtility hosts HouseholdHazardous WasteCollection Day everyApril to give residentsthe chance to dispose ofa variety of householditems, such as usedpaints, oil, pesticides,cleaners, batteries andpharmaceuticals.

CCWA contracted withCARE Environmental tocollect and properlydispose of the wasteduring the free, four-hour event on Saturday,April 27, 2019 at theW.B. Casey WaterResource Recovery Facility in Jonesboro.

CARE serviced 460 vehicles and processed 133,500 lbs. of waste. Theevent costs nearly $42,000 (the cost for the contractor collecting andproperly disposing of the items) and goes a long way to keeping thesepollutants out of our local creeks, streams and landfill. Clayton CountyPolice Department assisted this year with the collection of over-the-counter and prescription medication.

Thank you to all Clayton County residents and CCWA Ambassadorswho helped make the 2019 event a success!

AFTER

The SWU’sInvestigationTechnician andMaintenanceCrews work as ateam to providequality servicewhen it comes toresponding tocustomer calls.On average, a

customercomplaint was

responded to within twenty (20) hours. When a customer calls with astormwater issue, our Stormwater Investigation Technician is dispatched tocheck out every issue or complaint. During Fiscal Year 2018-19, he responded toover 611 customer related calls.

Part of the maintenance activity includes an aggressive inspection program. Thishelps our staff determine potential problem locations, as well as being compliantwith our Stormwater Permit. Using both internal staff and outside contractors,CCWA inspected the following structures over the past year:¥ Approximately 3,000 catch basin and inlets¥ Approximately 401,000 linear feet (76.0 miles) of storm drains¥ Approximately 123,000 linear feet (23.3 miles) of ditches

The Stormwater Maintenance staff of 17 employees (2 pipe repair crews, 1grading crew and 1 vacuum truck crew) addressed 2,737 work orders. Activitiesfrom these completed work orders represent:¥ Approximately 91,000 linear feet (17.2 miles) of storm drain lines¥ Approximately 20,000 linear feet (3.8 miles) of graded ditches¥ Approximately 720cleaned/repaired catch basins

Maintenance costs for this workcompleted between May 2018 and April2019 were slightly more than $3.0million. In addition to the maintenancework orders, CCWA solicited the help ofoutside construction firms to performlarger-scaled Capital ImprovementProjects (CIP). These projects includerepair methods of “Remove andReplace” (R/R), as well as a newertechnology called “Cured-In-PlacePiping” (CIPP).

Using both methods, CCWA performed48 large scaled CIP’s throughout thecounty last year. The 64 R/R and 11 CIPPjobs resulted in costs slightly over $4.6million. Combined, more than 13,000feet (2.47 miles) of pipe werereplaced/renewed using these methods.

STORMWATER UTILITY ANNUAL REPORT

Do you know your property’s Floodplain status???

What Lies Underneath?

Spotlight: Stormwater Investigation TechnicianStormwater Maintenance Crews Completed Nearly 2,740 Work Orders During FY 2018-19

Stormwater Utility Services include:

Flood insurance rate maps (FIRM’s), also known as Floodplain Maps, went into effect inJune 2017 for properties located in Clayton County. After years of extensive studiesand analyses, CCWA revised the County’s Floodplain Maps, as guided by FEMA. TheCounty’s maps were digitally updated in 2007, but several other factors requiredadditional field studies and desktop engineering to bring the maps up to date.

These updated maps are more precise than older maps because better flood hazardand risk data has been incorporated, and the latest science has been used to makethem more accurate. Flood risks change over time due to construction, development,environmental changes, floodplain widening or shifting, and other factors. Thesechanges send water flowing in new directions, creating flood risks that didn’t existpreviously—precisely why flood maps must be updated periodically.

The updated maps give staff a better understanding of local risk assessment,floodplain management, land use and emergency planning.

To determine your floodplain status, you may visit CCWA’s Floodplain Managementat http://www.ccwa.us/floodplain-mapping. On that page, you will find informationabout Floodplain Management. Click the link that follows the text, “To check thestatus of your property in Clayton County”. From there, take the following steps

1. Enter your information on the disclaimer form and “Accept” to continue. You will be taken to an internal Floodplain Mapping page where you will begin your search.

2. Click “Begin Search”.3. Enter your address number and street name. Click “Run Search.”4. Your personalized floodplain map will appear.

Please note, your Floodplain status is determined on whether the floodplainboundary touches your property. Your home, or important structure, may beelevated such that the lowest floor may be higher than the Base Flood Elevation(BFE). These maps may not provide you information on your particular structure. Itmay be necessary for the property owner to have an elevation certificate prepared,at their costs. Elevation certificates must be prepared by a Registered LandSurveyor or ProfessionalEngineer. CCWA does notprovide this service forproperty owners. Costs forthe preparation of anelevation certificate rangesfrom $500 to $1,500. It is upto the property owner toprocure these services.

If you have a mortgage onyour property, the lender mayrequire a Flood Insurancepolicy if your property iswithin the boundaries of afloodplain. An elevationcertificate may assist in reducing the cost of a flood insurance policy, if it can bedetermined the structure, in question, is elevated to where flooding risks areminimized. In some cases, the flood insurance policy may not be needed.

If you need additional assistance, please contact CCWA’s Floodplain Division [email protected] or at 770.302.1768.

Ever wonder whatall winds up in astormwater catchbasin on the roadside? Look at whatthe vac truck crewcleaned out of justone catch basin.This debris andlitter is what clogs a catch basin and causes road flooding whenthere is nowhere for rain water to go.

CCWA has a You Tube channel that featureseducational videos on:

➨ preventing stormwater pollution➨ finding and fixing leaks➨ proper disposal of fats, oils and greases ➨ and other topics

Ensuring customer satisfaction is often a difficult task, butStormwater Investigation Technician Jael Fuller always rises to the

occasion. When customerscall in with Stormwaterrelated issues, Jael is CCWA’sfirst line of defense. It’s hisjob to reach out to thecustomer and determinewhether the issue falls withinCCWA’s levels of service andif it does, determine the nextsteps to be taken. SinceStormwater is CCWA’snewest service, customersare not alwaysknowledgeable about CCWA’s

responsibility and theresponsibility of the property

owners. Jael makes sure to educate customers while still ensuringthey receive quality service.

When work needs to be done on a customer’s property, Jael isresponsible for scheduling work orders. It is imperative for him tobe as efficient as possible by including detailed comments on thetype of service that needs to be provided as well as pictures of thesite. This ensures that the crews responsible for doing the work cando so quickly and accurately. Heavy rain fall often leads to an influxof phone calls from customers, but Jael is always able to prioritizehis responses so in emergency situations customers receive help assoon as possible.

When CCWA needs temporary access to private property for aproject, Jael handles getting easements so that crews andcontractors are able to proceed with work. An easement is anagreement between CCWA and a private property owner that givesCCWA the right to access the private property. The private propertyowner still owns the property in the easement.

In his many years at CCWA, Jael says it has always been a greatplace to work. No matter what his day is like, he seems to alwaysend it with a smile.

When CCWA’s Stormwater Utility was created, CCWA inherited hundredsof miles of underground infrastructure without knowing if it was in goodshape or ready to fail. As part of our asset management approach tounderstanding this existing infrastructure running throughout the county,we decided to concentrate on large diameter stormwater pipes andculverts that run under roadways. Many of these pipes were installed yearsago using corrugated metal pipe with active streams and creeks flowingthrough them.

After years of continuous creek flow, many of these culverts are in poorcondition and failing. If they fail, they can cause personal and propertydamage from road cave-ins and flooding. CCWA’s goal is to assess andaddress these culverts before failure occurs. In some cases, problems arefound by you, the customers.

CCWA was called to a locationwhere a corrugated metal culvertwas used to allow flow from acreek to pass under Chilton Lane,just outside the city limits ofRiverdale. The residents observeda sinkhole forming in the roadway.Further inspections revealed asingle 60” corrugated metalculvert located under Chilton Lane,just west of Grayson Drive, in theJackson Estates Subdivision. In addition to the forming sinkhole, we foundthe culvert was severely corroded, and extreme sediment buildup at thedischarge end of the pipe.

Because of the culvert’s condition, CCWA was required to replace themetal culverts with reinforcedconcrete pipe (RCP). Because ofexisting utilities (water, sewer, andgas), above and below, CCWA hadto use arched pipe. Reinforcedconcrete pipe has 6” thick walls,therefore, to minimize the effectsto the other utilities, arched pipewas able to fit between thoseexisting utilities. With re-routingthe existing culvert, roughly 200’

of 60” Arched RCP was installed.Staff was required to re-route the pipe in order to provide additionalspacing away from the neighboring homes foundation. The existing metalculvert, next to the home, was grout filled to minimize any futuresettlement issue. Staff also replaced the existing damaged headwall atthe end of the culverts along with installing new precast structures (catchbasins) at the roadway. The downstream area was also stabilized with riprap (stone) to minimize erosion.After completion, the work area was restored and cleaned of existingtrash, debris and sediment. The replacement pipes are expected to have alife expectancy of at least 50 years of service, keeping this culvert issue-free for a long time. The overall cost of this repair is expected to beapproximately $215,000.

CCWA contracted withCARE Environmental tocollect and properlydispose of the wasteduring the free, four-hour event on Saturday,April 27, 2019 at theW.B. Casey WaterResource Recovery Facility in Jonesboro.

CARE serviced 460 vehicles and processed 133,500 lbs. of waste. Theevent costs nearly $42,000 (the cost for the contractor collecting andproperly disposing of the items) and goes a long way to keeping thesepollutants out of our local creeks, streams and landfill. Clayton CountyPolice Department assisted this year with the collection of over-the-counter and prescription medication.

Thank you to all Clayton County residents and CCWA Ambassadorswho helped make the 2019 event a success!
